jtek 0 Posted April 16, 2007 right, been fitting an immobiliser today, got all of the power and accessory and ground connections in, and that leaves the two wire loops to go into the circuits to immobilise them. i am looking to cut the fuel pump and the starter motor ideally, however, the haynes manual seems to be a bit flaky with its wiring diagrams and the wire numbers. so does anybody know which are the easiest wires to cut/numbers and their location? the car is a 1989 1.6 gti. the immobiliser is a toad sterling touch key. any advice would be greatly appreciated as i am a bit screwed at the moment lol Share this post Link to post Share on other sites
jimbean 0 Posted April 16, 2007 fuel pump is good to find open fuse box and you will see loads of big conectors with lots of wires not on board, but above in the spagettie, there is 1 single conector in the mass of wires.. this is the fuel pump conection the wires are thick and i think white with black conectors.. male and female conect 1 wire to 1 side of the cut loop and same on other. the starter is one of the conectors on the fuse board above the relays to the left of the board to find it, pull it out and try to start it when you have the right 1 it wont turn over. it will we the thick wire in the block and then do the same with the loop wires... cut and connect Share this post Link to post Share on other sites
Mikey S 29 1 Cars Posted April 16, 2007 fuel pump wires are on the tachymetric (sp?) relay under the dash. iirc its a white wire. the starter motor wire is on the brown plug under the dash to the left of the steering column. thats a big blue wire. as for wire numbers, i dont have my haynes to hand at the min, but if your still stuck i will see if i can post them up tommorow.

jtek 0 Posted April 16, 2007 thanks guys, there is one concern i have, the immobiliser wiring is very thin gauge, we reckon only good to carry 5A realistically, although the instructions claim the internal relays on the immobiliser can carry 18A, do you know if this will be an issue with the currents running through the suggested wires to cut? thanks Share this post Link to post Share on other sites

Richie-Van-GTi 71 2 Cars Posted April 17, 2007 I wouldnt bother with starter wire as a car can be bumped of if they put power on the fuel pump. Id put it with ecu and fuel pump, that way they wont get it running without removing the immobiliser. Share this post Link to post Share on other sites
TEKNOPUG 3 Posted April 17, 2007 Hack into the two thick wires that lead from the tachy relay to the fuel pump to cut the fuel supply. Then go into the ignition loom by following the wires that lead from the ignition barrel and splice into those. Share this post Link to post Share on other sites
jimbean 0 Posted April 18, 2007 but if you think about it if you were a car thief where would you start the car from the ign wires... if all the immob wires are connected to it or close to.. it it make his job of stealing you motor very easy... thats why i plumb in the wires as far away from there as i can... thus making it difficult for the slimey little toad to get my pride and joy Share this post Link to post Share on other sites
